Graphing Quadratic Functions
Complete each of the following steps for the Quadratic Function $\displaystyle {f{{\left({x}\right)}}}={2}{x}^{{2}}-{4}{x}+{1}$
1) Identify the coefficients a, b and c: a= b=c=		$\displaystyle {f{{\left({x}\right)}}}={2}{x}^{{2}}-{4}{x}+{1}$ Clear All Draw:
2) Graph the function on your calculator
3) Does the graph open up or down and why?: Select an answer Opens Up, a < 0 Opens Up, c > 0 Opens Down, c < 0 Opens Down, a > 0 Opens Up, a > 0 Opens Down, a < 0
4) Write the Vertical Intercept as an Ordered Pair
5) Plot the Vertical Intercept on the graph using the point tool
6) Draw the function neatly on the graph using the poly tool by plotting the highest (or lowest) point and one other point.
